Bladder Augmentation
Ileocecoplasty technique
- Place patient supine with arms out, place in trendelenberg, do not need to hyperextend bed, give cefazolin + metronidazole for bowel coverage
- Tip: can place foley prior to prep/drape, but need accessible to fill bladder during case
- Make midline incision from pubic symphysis to slightly above umbilicus to access hepatic flexure, divide layers and enter peritoneal cavity
- Free up ascending colon from retroperitoneal attachments, can see kidney/duodenum underneath, free up to hepatic flexure
- Mark 10-15cm terminal ileum and 10-15cm cecum/ascending colon, identify mesenteric blood supply to ensure presence, can perform doppler and IC green before stapling
- Create mesenteric window with tonsil/bovie, then divide mesentery up to bowel with ligasure, then staple bowel
- Take bowel ends, create opening and staple together (ensure new conduit is inferior), then close the hole either with new staple load or 2-0 vicryl interrupted, can oversew with 2-0 silks
- Fill bladder with 200mL water, then open bladder at dome transversely, place traction 2-0 vicryl stitches on flaps for access
- Ensure cecum lays comfortably on bladder, then open antimesenteric end of cecum
- Open end of ileum, place 12Fr catheter, grasp redundant tissue with allis clamps, and staple off excess ileum (taper off towards ileocecal valve)
- Switch for 16Fr catheter, place plication (imbricating) sutures with 2-0 vicryl on antimesenteric side, checking that catheter pops in/out after tying each one down
- Secure cecum to bladder with 2-0 vicryl - place 3 stitches and run each one, try to have knots on outside of bladder
- Place drain - make separate stab incision, then push tonsil clamp from skin into abdomen, grasp drain and pull through, secure with nylon stitch
- Cut out circle on skin at ideal channel site, remove underlying subcutaneous fat (expose with army/navy retractors), create small cruciate incision on fascia, should be large enough to allow one finger through
- Insert babcock clamp through channel incision into abdomen, grasp channel and bring out through skin, stitch to skin with 3-0 vicryl (do not stitch mesentery), make sure balloon is inflated, should have either separate suprapubic or urethral foley as safety valve
- Closure - #1 PDS x2 (meet in middle) for fascia, then 3-0 vicryl to bring subcutaneous tissue together and staples for skin
